Despite the evidence that fire is a necessary element, over most of the past century people have feared and suppressed it whenever possible. Lightning has always been, and still remains the primary cause of wildland fires. On average, Rocky Mountain National Park experiences three to seven lightning caused fires per year. Other factors - including past logging practices, grazing levels and climatic conditions - have also contributed to changes in natural fire regimes.
As a result of this exclusion of fire, there has been an unnatural fuel buildup of live, dead and diseased trees, pine needles, shrubs and grasses in some areas of the park. This accumulation of fuel now presents extreme hazards to the health of forests, soil, watersheds and wildlife. It also is a primary concern to people living in these areas, as well as to the taxpayer that has to pay for the suppression costs of major wildfires.
